用放射免疫法分别检测了65例牙周炎患者及40例健康人唾液SIgA和血清IgA含量的变化。结果显示,患病组唾液SIgA和血清IgA含量明显高于正常对照组(P<0.01);青少年牙周炎与成人牙周炎患者唾液SIgA和血清IgA的含量无显著差异(P>0.05)。提示唾液SIgA及血清IgA含量的变化,有助于判断牙周炎患者的机体免疫状况。
The changes of saliva SIgA and serum IgA in 65 patients with periodontitis and 40 healthy people were detected by radioimmunoassay. The results showed that salivary SIgA and serum IgA levels in the sick group were significantly higher than those in the normal control group (P <0.01). There was no significant difference in salivary SIgA and serum IgA levels between adolescent periodontitis and adult periodontitis (P> 0.05). Suggest saliva SIgA and serum IgA levels change, helps to determine the body's immune status of patients with periodontitis.
